D2790 is the CDT code for a full cast high noble metal crown — a crown made entirely of high noble metal (such as high-gold alloy), with no porcelain. Full-metal gold crowns are exceptionally durable, gentle on opposing teeth, and well-fitting, used on back teeth where strength and longevity are prioritized over tooth-colored aesthetics.
What D2790 means
D2790 covers a crown — full cast high noble metal. "D" is dental, "27" is the crowns group, and "90" is this full cast high-noble crown. A full cast metal crown is made entirely of metal (cast as one piece), covering the entire tooth, with no porcelain or tooth-colored veneer — so it's metal-colored (gold or silver-colored). This crown is made of high noble metal — the premium category (over 60% noble metal, with at least 40% gold), typically a high-gold alloy. So it's a full gold (high-noble) crown.
Full gold crowns are renowned for their exceptional durability and longevity, their gentleness on the opposing teeth (gold wears at a rate kind to natural enamel), and their precise fit and marginal seal — making them an excellent, long-lasting restoration, particularly for back teeth where the metal color isn't a major concern.
The full cast metal crown codes are by metal type: high noble (D2790, this one), predominantly base metal (D2791), and noble metal (D2792); titanium is D2794. Full-metal crowns differ from PFM crowns (D2750+, which have porcelain over metal) and all-ceramic crowns (D2740) by being entirely metal (no tooth-colored surface). Gold crowns have a long, proven track record. Coverage is under major restorative benefits, often around 50 percent, with frequency limits; the high noble metal/gold content affects the fee and varies with metal prices.
When it's typically used
D2790 is reported for a full cast high noble metal (gold) crown — a crown made entirely of high-noble metal, used on back teeth where exceptional durability, longevity, and gentleness on opposing teeth are prioritized and the metal color isn't a major aesthetic concern.
How much does D2790 cost?
A full cast high-noble (gold) crown is a significant fee, often roughly 900 to 2,000 USD depending on region and the gold market (the high gold content significantly affects the cost, which varies with gold prices) — reflecting the substantial amount of high-noble metal (a full crown's worth). It's exceptionally durable and long-lasting, offering excellent long-term value.
Is D2790 covered by insurance?
Covered under major restorative benefits, often around 50 percent, with frequency limits (e.g., once per tooth per 5-10 years). The high noble metal/gold content significantly affects the fee (and varies with gold prices), and some plans may apply an alternate-benefit downgrade toward a base-metal crown rate (with the patient covering the difference for the gold). Documentation supports the claim. The substantial gold content makes verifying coverage and cost worthwhile.
Why full gold crowns are exceptional
Full gold (high noble) crowns are renowned as exceptional restorations, and understanding why clarifies their enduring value.
Full gold crowns have several outstanding qualities. Exceptional durability and longevity: gold crowns are renowned for lasting a very long time — often decades — frequently outlasting other crown types. Gold is strong yet not brittle (it doesn't crack or chip like porcelain can), resists wear, and is highly durable, making gold crowns remarkably long-lasting and reliable. Gentleness on opposing teeth: gold wears at a rate similar to natural tooth enamel, so a gold crown doesn't aggressively wear down the opposing teeth that bite against it — a kindness to the rest of the dentition (some harder materials, like certain ceramics, can wear opposing teeth more). Precise fit and marginal seal: gold can be cast and fitted with excellent precision, providing very accurate margins (where the crown meets the tooth), which gives a good long-term seal and reduces the risk of decay at the margins. Biocompatibility: high noble (gold) metal is excellently biocompatible and corrosion-resistant. These qualities combine to make full gold crowns exceptional, long-lasting, biologically-kind restorations.
The one trade-off is appearance — a gold crown is gold-colored, clearly metal, not tooth-colored, so it's visible as gold. This makes it unsuitable for visible teeth where aesthetics matter. But for back teeth (especially molars, less visible), where the metal color isn't a concern, a gold crown's exceptional durability, longevity, and gentleness make it arguably the best long-term restoration. This is why gold crowns, despite the trend toward tooth-colored restorations, remain valued and are considered by many dentists the gold standard for durability and biological kindness on back teeth. For patients, understanding why full gold crowns are exceptional — exceptional durability and longevity, gentleness on opposing teeth, precise fit, and biocompatibility — clarifies their enduring value. They're outstanding, long-lasting restorations for back teeth. The dentist may recommend a gold crown for a back tooth where these benefits are prioritized. Understanding gold's exceptional qualities helps patients appreciate why a gold crown might be chosen — for unmatched durability, longevity, and biological kindness on a back tooth, despite its metal appearance, offering an excellent, time-tested, long-lasting restoration.
When a full metal crown is chosen
A full metal crown suits particular situations, and understanding when it's chosen clarifies its role.
A full metal (gold) crown is typically chosen for back teeth where several factors favor it. The metal color isn't a concern: on back teeth (molars, and to some extent premolars toward the back), the metal color is much less visible (or not visible) during normal speaking and smiling, so the gold appearance isn't an aesthetic issue. Durability and longevity are prioritized: for a tooth where maximum durability and a long-lasting restoration are wanted (perhaps a heavily-used molar, or for a patient who values longevity), the gold crown's exceptional durability is advantageous. Gentleness on opposing teeth is valued: if preserving the opposing teeth from wear is a priority, gold's gentleness is beneficial. Heavy chewing forces: back teeth bear heavy forces, where gold's durability handles them well. Adequate space/preparation considerations: gold crowns can sometimes be made with less tooth reduction than some other crown types in certain aspects, which can be advantageous.
So a full metal crown is chosen for back teeth where durability, longevity, and gentleness are prioritized and the metal color is acceptable. It's not chosen for visible front teeth (where tooth-colored crowns are used for aesthetics). Some patients and dentists specifically prefer gold for back teeth for its proven longevity. The dentist determines whether a full metal crown is appropriate, weighing the durability benefits against the metal appearance and the tooth's location. For patients, understanding when a full metal crown is chosen — for back teeth where durability, longevity, and gentleness are prioritized and the metal color is acceptable — clarifies its role. It's the durable choice for back teeth where appearance isn't a concern. The dentist recommends it when these factors align. Understanding when it's chosen helps patients see why a full metal (gold) crown might be recommended — for an exceptionally durable, long-lasting restoration on a back tooth where the metal color is a non-issue and the longevity and gentleness are valued, offering excellent long-term value for the right tooth.
Gold crowns vs tooth-colored crowns
Gold crowns and tooth-colored crowns involve a trade-off, and understanding it clarifies the choice.
The choice between a gold crown and a tooth-colored crown (PFM or all-ceramic) comes down to weighing durability/gentleness against aesthetics. A gold crown offers exceptional durability and longevity, gentleness on opposing teeth, and a precise fit — but it's gold-colored (not aesthetic). A tooth-colored crown (PFM, with porcelain over metal, or all-ceramic) offers a natural appearance (tooth-colored) — suiting visible teeth and aesthetic priorities — with good durability (modern ceramics are strong), though porcelain can chip (unlike gold), and some hard ceramics can wear opposing teeth more than gold. So the trade-off is gold's durability, longevity, and gentleness versus tooth-colored crowns' aesthetics.
The choice largely depends on the tooth's location and priorities. For a visible tooth (front teeth, and visible premolars) or where aesthetics matter, a tooth-colored crown is the clear choice. For a back molar where appearance isn't a concern and maximum durability/longevity/gentleness are prioritized, a gold crown can be the better long-term choice. Patient preference also plays a role (some prefer everything tooth-colored, others value gold's proven longevity for back teeth). The trend toward tooth-colored restorations (especially with strong modern ceramics) has made tooth-colored crowns very popular even for back teeth, but gold remains valued for its unmatched durability and gentleness where appearance isn't a concern. The dentist discusses the options, weighing the tooth's visibility, durability priorities, and aesthetics. For patients, understanding the trade-off — gold offering exceptional durability, longevity, and gentleness but being metal-colored, versus tooth-colored crowns offering aesthetics with good durability — helps them choose. For a back tooth prioritizing longevity, gold; for a visible tooth or aesthetics, tooth-colored. The dentist's recommendation considers the tooth and priorities. Understanding the trade-off helps patients see why a gold or a tooth-colored crown might be chosen, balancing gold's durability and gentleness against tooth-colored crowns' aesthetics, guided by the tooth's location and the patient's priorities.
The long-term value of a gold crown
A gold crown offers excellent long-term value, and understanding this clarifies why its cost can be worthwhile.
A full gold crown has a significant upfront cost (reflecting the substantial high-gold metal content, which varies with gold prices), but it offers excellent long-term value for several reasons. Exceptional longevity: gold crowns are renowned for lasting a very long time — often decades — frequently outlasting other crown types. A restoration that lasts decades, rather than needing replacement every 10-15 years (as some crowns might), provides excellent value over time, avoiding the cost and effort of repeated replacements. Reliability: gold's durability (not chipping or cracking like porcelain can) makes gold crowns reliable, with fewer failures. Protecting the tooth: a long-lasting, well-sealed gold crown protects the underlying tooth well over the long term (the precise margins reducing decay risk), helping preserve the tooth. Gentleness: gold's kindness to the opposing teeth preserves those teeth too. So over a lifetime, a gold crown's longevity and reliability can make it more economical and less troublesome than crowns needing more frequent replacement, despite the higher upfront cost.
This long-term value is part of why gold crowns are valued for back teeth — the upfront investment in a durable, long-lasting restoration pays off over time. Of course, the gold crown depends on the underlying tooth staying healthy (good hygiene to prevent decay at the margins) and proper care, but the gold itself is highly durable and long-lasting. For patients, understanding that a gold crown offers excellent long-term value — through its exceptional longevity (lasting decades), reliability, and tooth protection — clarifies why its higher upfront cost can be worthwhile. A restoration that lasts a very long time provides value over the years. The dentist can discuss whether a gold crown's long-term value makes it a good choice for a back tooth. Understanding the long-term value helps patients see the gold crown's cost in perspective — as an investment in an exceptionally durable, long-lasting restoration that can serve for decades and provide excellent value over time, particularly for a back tooth where its durability and longevity are realized, making the upfront cost worthwhile for the lasting, reliable restoration it provides.
